Because the changing of source water, obvious variety of total degree hardness index about the new source water caused the difference on residents'taste. 结果显示因供水水源的更换,新供水系统总硬度指标显著变化,导致口感差异;
The hydrogenation can be controlled to produce any degree of hardness desired in the product. 为了生产所需要的任何硬度的产品,可对氢作用加以控制。
That degree of hardness accounts to be applicable to the black metals and have the color metals with the degree of hardness measurement of the nonmetal material. 液晶屏数显洛氏硬度计适用于黑色金属、色金属和非金属材料的硬度测定。
The function's proceeding every kind of degree of hardness parameter converts automatically mutually, discriminating to try an environment for the minimum thickness experiments with the measurement temperature. 该机能进行各种硬度参数相互自动换算,鉴别试件最小厚度和测定试验的环境温度。
If a low degree of hardness is satisfactory, through-hardening is probably the most desirable heat treatment process to be used because of its inexpensiveness. 要是对强度的要求较低,群体淬火有可能是最适当的热处理方法,由于它的花费不高。
